Air ram design and retrofit into a german FWB 124 ??? ..... Doable or not ?

Question of just not knowing ??

the FWB 124/127 series rifles hold them self cocked via a center post that go's into the center of spring guide on face of the trigger assembly contained within spring tube.

Not been into many spring guns and just was wondering if this type action can use Air ram / Nitro piston instead of the coil spring

FWB Sporters employ a stemmed piston and I dont think a ram conversion would be your best route to take. A JM kit would be much better and keep the velocity in the range that the rifle was designed to shoot at, as well as taking full advantage of the fine match grade rifled FWB barrel.
